A bug in python-pyscopg2-2.0.14 causes a reference leak when cumin-data updates objects in the database. Specifically, the bug manifests when cursor.mogrify(operations, params) or cursor.execute(operations, params) is called and the 'operations' string references the same value from 'params' more than once.
Long-running instances of cumin can leak significant amounts of memory.
The _mogrify() routine in cursor_type.c was patched in python-pscyopg2-2.0.14-3.
This reference leak has been repaired and no longer is an issue when cumin-data updates obejcts.
